STARTING DEVICE.

Specification of Letters Patent.

Patented Feb. f2, 1918.

Application filed March 6, 1917. Serial No. 152,508.

To all whom it may concern:

Be it known that I, JOSEPH ORR, a citizen of the United States, residing at Verona, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Starting Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in starters for internal combustion engines, such as are used fordriving automobiles, and the like; and, the invention has reference, more particularly, to a novel and manually operated starting mechanism of such a construction that one stroke of an o aeratin lever will set the startin mechanism in motion, and by its motion will cause more than one complete revolution of the engine-shaft and rapid reciprocatory movements of the piston of the engine.

The present invention, therefore, has for its principal objects a novel, simple and efiiciently operating starting mechanism for internal combustion engines, and the like, which can be readily operated by the single stroke of a lever under the control of the chauffeur seated in the vehicle, to rapidly start the motor or engine and at the same time, if desired, the automobile with the driving axle of which the motor or engine is connected in any usual manner.

The invention has for its further object the novel arrangement of a clutch-device operating with relation to a worm-shaft in such a manner, so that a movement of the starting lever in one direction will actuate the wormshaft so that the motor or engine is started, but which clutch-device works in such a manner so that the operated and moved parts of the starting mechanism will return to their normal initial positions without interfering with the continuing revolutions of the engine-shaft and the continuing driving operations of the engine.

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of my present invention.

"With the various objects of the present invention in View, the said invention consists, primarily, in the novel starting mechanism for internal combustion engines hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the con struction of the said parts, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claim which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a front elevation of a starting mechanism embodying the principles of the present invention.

Fig. 2 is a transverse vertical section of the same, said section being taken on line 22 in said Fig. 1, looking in the direction of the arrow 00; and Fig. 3 is a horizontal section of the starting mechanism, said section being taken on line 3-3 in said Fi 2, looking in the direction of the arrow 7 the clutch-device, however, being a sectional representation of the same, taken in a plane at right angles to the sectional plane on said line 33.

Similar characters of reference are employed in the said above described views to indicate corresponding parts.

Referring now to the said figures of the drawings, the reference-character 1 indicates a suitable frame which is provided with suitably formed members, as 2-, having perforated ears or lugs 3 for the reception of bolts by means of which the frame may be secured in a desirable position to the framework of an automobile, or the like, and usually in a vertical position. It will be understood, however, that other means may be employed for securing said frame 1 in its operative position. At its opposite ends, the said frame 1 may be made with endpieces, as 4, which are provided with the bearing-members 5 and 6. a The referencecharacter 7 indicates a shaft which has one of its end-portions rotatably mounted in the bearing-member 6, and has its other endportion rotatably mounted in the bearing member 5. Motion of the shaft in said bearing-members 5 and 6 in the direction of its longitudinal axis is prevented by means of devices, as 8, which are pinned to said shaft by means of pins 9, although it will be evident, that any other suitably constructed means may be provided for, overcoming any movement longitudinally of the said shaft in' said bearing-members, as will be clearly understood.

Loosely mounted upon said shaft 7, by means of a bearing-portion 10 in the closed end 11 is a hollow cylinder12, the opposite and open end of said cylinder 12 being suitably closed by means of a mounting disk or plate 13 which is provided with a bearingportion 1 1, for loosely supporting said disk or plate upon said shaft 7 and'atthe same time properly mounting the said hollow cylinder 12 upon the shaft. Upon that portion of the said shaft 7 within the said cylinder 12 is suitably secured by means of pins-15, or otherwise, a clutch-element, as 16, formed in its cylindrical or arc-shaped portions, see Fig. v2, of the drawings, with longitudinally extending recesses or cut-away parts, as 17,

preferably of the conformation shown, and in which are disposed so as to roll in said recesses or cut-away parts suitable rollers, as 18. Pockets, as 19, may also be provided, in which are disposed suitable coilsprings 20 which bear against the said rollers. The result is that when the hollow cylinder 12is rotated in the direction of-the arrow ein said figure, in the manner to be hereinafter 'set forth, the rollers 18 are caused to roll in outward directions toward the peripheral surface-portlons of the cylindrical or arc- Y shaped members of the clutch-element 16 and to sufficiently bind upon the inner surface-portions of the hollow cyllnder 12, so

that the rotary motion of said cylinder in the direction of the said arrow 2 will correspondingly rotate the clutch-element 16. and consequently also the shaft 7, the rotary motion of the said shaft being conveyed by means of a sprocket-wheel 21 and a linle chain 22, or other suitable conveying means, to the engine-shaft 23, or other suitable element which is to be started. The rotary motion of the hollow cylinder 12 in a direction reverse from that indicated by the arrow 2 will release the frictional engagement of the rollers 18, and will not interfere with the continuing rotary motion of the shaft 7 now idly running in the direction of said arrow 2 simultaneously with the started mo V tor or engine.

As shown, the said hollow cylinder 12 is formed in its outer cylindrical surface with" vided with the oppositely projecting and perforated flange-members 27 and 28, secured together by means of bolts 29 and nuts 30, or othe'r suitable securing means. The fiange-members 27 are recessed or cut away, as at 31 so that each pair of secured flangemembers 27 and 28 will provide a fork or embracing portion slidably mounted upon a longitudinally extending piece of the previously-mentioned frame Extending from the said flanges 28 are perforated lugs 82 in which are arranged the screw-threaded end-portions 34 ofsuit able connecting rods or links'33, suitably se cured in position by meansof nuts 35 and 36 placed on opposite sidesof said lugs and screwed upon the screw-threaded portions 34: of the said rods or linksSS; The said rods or links-are slidably disposed-within suitable guiding members 37 connected is a connecting plate or bar 41 formed with a perforated ear or lug 4.2 which carriesapivot-pin orbolt 4C3. Operatively connected with the said pin or bolt' lS is the slottedend-portion' 45 of an operating lever 44,.

said lever being pivotallymounted asat 16, upon a suitable location upon the framework of the automobile. If desired, the said levert4 may have attached thereto one endportion of a coiled spring lfi, the other endportion of thegsaid spring being suitably attached, as at 48, to the frame-Work of the automobile, as will be evident; The purpose of said spring is, afterrthe upper por tion of the lever has been moved in the direction of the arrow u in. said Fig. 1, to return the said lever and the parts operated thereby to their normal initial" positions, after the lever has been released by the op erator. V

To prevent rattling of the said lever, due to possible lost motion, there may be provided a compensating device in the form of a roller, as 49, rotatably mounted upona pin 50, also secured upon the frame-work of the automobile, a wire or othersuit-able flexible connection, as 51', being. coiled upon. said" roller- 48, and: having its respectiveflend portions52 and 53 attached to thes'aid lever 14- andthe said plate or bar 41in any suitable manner, as will be clearly under'-' stood from aninspection of said Fig. 1 of the drawings. 'lh1s--com-pensat1ng device may, however,be dispensed -w1th, if desired.

The operation of thestart-ing mechanism,

briefly, is as follows?- l/Vhenthe lever 44 ismoved in the? direc? l 7 tion ofthe. arrow .u, the plate or bar il'and the connecting rods or links 33 Will move the cross-head in the direction of the arrow 00 in said Fig. 1, thereby properly revolving the hollow cylinder 12, and by means of the clutch-device, herein-above described, correspondingly revolving the shaft 7, which in turn starts the motor or engine. As soon as the lever 44 is returned to its normal position, the clutch-device assumes its released relation, whereby the cross-head and the rods or links 33 and plate or bar 41 move back to their normal initial positions, with out interfering with the continuing revolutions of the shaft 7 and the continuing workings of the motor or engine.

I am fully aware, that changes may be made in the general arrangements and combinations of the several devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses ofthe claim which are appended thereto.
